An Army Group Royal Artillery (AGRA) was a British Commonwealth military formation during the Second World War and shortly thereafter. Generally assigned to Army corps, an AGRA provided the medium and heavy artillery to higher formations within the British Army.

The Bermuda Militia Artillery was a unit of part-time soldiers organised in 1895 as a reserve for the Royal Garrison Artillery detachment of the Regular Army garrison in Bermuda. Militia Artillery units of the United Kingdom and Colonies were intended to man coastal batteries in times of war, which were manned by under-strength numbers of regular army gunners in peace time. The unit was embodied during both world wars, fulfilling its role within the garrison, and also sending contingents overseas to more active theatres of the wars.

This is a list of British Army Yeomanry Regiments converted to Royal Artillery. In the aftermath of the First World War 25 Yeomanry regiments of the British Army were transferred to the Royal Artillery between 1920 and 1922 with another one – the City of London Yeomanry – reduced to a battery in another regiment. A further seven regiments were converted during the Second World War.

The Moonlight Batteries were Searchlight units of Britain's Royal Artillery that specialised in providing 'artificial moonlight', otherwise known as 'movement light' or 'Monty's moonlight', for ground operations during the latter stages of World War II.

The Royal Artillery Mounted Rifles are detachments of the British Army's Royal Artillery when deployed as mounted infantry. The unit was first developed towards the end of the Second Boer War which was characterised by guerrilla warfare. There was little call for traditional units of field or horse artillery but high demand for mounted infantrymen to counter the highly mobile Boer commandos. By the end of the war around 2,000 artillerymen were acting in the mounted infantry role. A similar force was deployed to Ireland in the early 1920s to counter guerrilla tactics used by Irish republicans.

The Royal Field Artillery (RFA) of the British Army provided close artillery support for the infantry. It came into being when created as a distinct arm of the Royal Regiment of Artillery on 1 July 1899, serving alongside the other two arms of the regiment, the Royal Horse Artillery (RHA) and the Royal Garrison Artillery (RGA). It ceased to exist when it was amalgamated with the Royal Garrison Artillery in 1924. The Royal Field Artillery was the largest arm of the artillery. It was responsible for the medium calibre guns and howitzers deployed close to the front line and was reasonably mobile. It was organised into brigades, attached to divisions or higher formations.

The Royal Garrison Artillery (RGA) was formed in 1899 as a distinct arm of the British Army's Royal Regiment of Artillery serving alongside the other two arms of the Regiment, the Royal Field Artillery (RFA) and the Royal Horse Artillery (RHA). The RGA were the 'technical' branch of the Royal Artillery who were responsible for much of the professionalisation of technical gunnery that was to occur during the First World War. It was originally established to man the guns of the British Empire's forts and fortresses, including coastal artillery batteries, the heavy gun batteries attached to each infantry division and the guns of the siege artillery. The RGA was amalgamated with the RFA in 1924, from when the only two arms within the Royal Regiment of Artillery are the Royal Artillery and the Royal Horse Artillery.

The Royal Horse Artillery (RHA) was formed in 1793 as a distinct arm of the Royal Regiment of Artillery to provide horse artillery support to the cavalry units of the British Army..
